Explanation:
6.
A star is observed to cross the meridian (due south) at an elevation of
34°, as seen from an observatory sited at a latitude of 42° north. What is
the declination of the star? At the moment of transit, a clock running on
Universal Time (UT) read 03 h 16min 24 s. At the previous midnight, the
sidereal time was 14h 38 min 54 s. Calculate the Right Ascension of the
star.

Astrologers believe that we are going through 12 zodiac "ages that each last 2160 yr. This is because the Earth's rotation axis precesses with a 12 x 2160 26,000 yr period. This means that Polaris, the current north star, won't always be the north star This precession is due to a gravitational torque applied by the sun and moon due to the slight non-spherical shape of the earth. Based on its size, shape, and rotation rate, what is the angular momentum of the earth in kg m/s? Assume a spherical earth.
